New South Wales has recorded nine new coronavirus cases after 60,000 residents came forward for testing in the past 24 hours.
Seven of the new cases were linked to the Avalon cluster, which has now swelled to 104 infections.
Premier Gladys Berejiklian said she was extremely pleased with the number of test results recorded.
"I nearly fell off my chair, literally, when we realise that 60,000 people came forward to testing last night, that many people and a 24-hour period is outstanding," she said.
